Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the HTTP method (GET) and the endpoint path, which is mild behavioral context, but it does not disclose response shape, error conditions, or any side effects. This is acceptable but not exceptional given the low-risk operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and front-loaded with the key READ-ONLY and resource information. Slight redundancy exists between 'Retrieve bank statement transaction' and 'Endpoint for retrieving a single bank statement transaction,' but the overall structure is efficient and scannable.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read-only retrieve with two required path parameters and strong annotations, the description is nearly complete. The endpoint path and the word 'single' give the agent enough context to invoke it correctly. The only notable gap is not distinguishing statement transactions from the closely related ledger transactions sibling, but the tool name itself makes this reasonably clear.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Although schema description coverage is 0%, the description's inclusion of the full URL template 'GET /bank-accounts/{bank_account_id}/statement-transactions/{id}/' clarifies that both parameters are path parameters and conveys their roles. This adds meaning beyond the bare schema, though it still does not explain value formats or constraints.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states a specific verb and resource: 'Retrieve bank statement transaction' and 'Endpoint for retrieving a single bank statement transaction.' The word 'single' distinguishes it from the list sibling, and the resource path specifies the exact object being retrieved. It is unambiguous and immediately actionable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied by the retrieve semantics and the word 'single,' but the description does not explicitly state when to choose this tool over alternatives such as the list endpoint or the ledger transactions retrieve endpoint. With a large sibling set, a brief when-to-use/when-not-to-use note would strengthen this dimension.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
